1 Safety and requirements for product use
1.1 Safety
Caution
Glare and eye irritation
With regard to the blue light hazard, the Checkbox Compact exceeds the limit
values of the free group in accordance with DIN EN 62471:2009-03. Therefore,
an assignment to risk group 1 applies for the blue light hazard. Looking at the
light source for a long or prolonged period can dazzle your eyes and cause irrita­
tion. Take measures to prevent eye exposure:
• Do not remove any housing parts.
• Only mount/remove the prism support when the power supply is switched off.
• Mount the Checkbox only in its original state with closed, intact housing.
• Mount or remove the Checkbox only when the power supply is switched off.
• Mount the Checkbox in such a way that it is not possible to look directly into
the light beam.
• Also take measures to ensure that if the light beam is reflected off mirrored or
reflective objects, it does not pose a hazard (for example, by providing screen­
ing).
• Do not look directly into the light beam and do not direct the beam into the
eyes of other people.
Ordinary light sources are divergent, i.e. the illuminated area becomes
larger as the distance from the light source increases. As a result, the risk
of eye injury decreases as the distance from the light source increases.
However, as the Checkbox Compact uses parallel light, the risk of eye
injury is not reduced as the distance increases; this applies to both looking
directly at the beam and looking into the beam via a reflective surface.
